I'd just cleaned inside and out, topped up oil & water and she'd sailed through the MOT, the sun came out, hood down.... but then...
Driving slowly and suddenly there was a noise like a small backfire and the engine cut out. All the dash lights were on, as though I was about to start the engine. Coasted to a halt, turned the key and 'whirr' -as if the starter is spinning, but not turning the engine.
Sitting at the lights earlier, I had thought the engine had a bit of a rattle that I didn't recognise. Other than that, everything's been as normal.
I keep thinking maybe the 'C' word (cambelt?). The engine was rebuilt around 80k km -it's now done 105k. Regularly serviced.
Can anyone suggest things to check to help a diagnosis?
